Please provide the contents of /var/log/asterisk/full, as plain text, with verbosity at least 5, and with “pjsip set logger on” or “sip set debug on”, as appropriate, in effect. I’m not going to look at wireshark one line summaries, mixed in with irrelevant traffic.
In particular, I suspect full details of the SDP are going to be required.
Also, if at all possible, generalise this, as at the moment, it is difficult for someone to answer who doesn’t have both in depth knowledge of the Algo product line, and singlewire.
